JOHNF. PACKER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE DAVID BRADLEYMANUFACTURING COMPANY, OF SAME- PLACE.

PLOW.

SPECIFICATION forming part of Letters Patent No. 353,495, dated November30, 1886.

Application filed October 28, 1884. Serial No. 146.108. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. PACKER, residing at Chicago, inthe county ofCook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Plows, of which the followingis a full description, reference being had to the accompanying drawings,in which Figure 1 is a side elevation; Fig. 2, a top or IO plan view;Fig. 3, aside elevation of the colter; Fig. 4, a detail showingcolter-arm and clamps; Fig. 5, a side elevation of the forward end ofthe plow-beam; Fig. 6, a detail, partlyin section, showing the lock forthe clevis.

This invention relates to certain improvements in the manner ofattaching the clevis, and has for its objects to enable the clevis to bereadily changed for the draft required and locked firmly in the positionat which it is set.

The objects of my invention Iaccomplish in themanner and by the meanshereinafter described and claimed, and illustrated in the accompanyingdrawings.

In the drawings, A represents the plowbeam, made of wood or othermaterial, as usual.

Bis the standard, the upper end of which has a flange orsupport, b, onwhich the under surface of the beam rests when the parts are together,and, as shown, the beam and stand- 0 ard are secured together by a bolt,a, which passes through the beam and through the flange b. This standardB on its outer face is provided with a lug or projection,c, the underface of which is formed beveling, and this lug 5 or projection may becast with the standard or be secured thereto in any firm manner.

0 is the colter-blade, having its forward side provided with acutting-edge, as usual, and this blade has a rearward extension or arm,

0, one side of which on both edges is formed beveling to correspond withthe bevel on the under face of the lug c, or nearly so, and thesebeveled edges 0 of the arm, as shown, extend the full length of the armto facilitate manufacture; but they might be of a less length properlylocated in relation tothelo'cking lugs or clamps. The upper bevelededgec passes underneath the lug or clamp c, and the lower beveled edge 0is engaged by the beveled face of amovable lug or clamp, c, which isattached to the face of the standard by a bolt or screw,

0, and this lug or clamp c is located, in relation to the arm orextension 0, so as to be, when in position, near the outer end of thearm, as shown in Fig. 1. The lug 0 forms a fulcrum, and the lug c thepower by which, when the lug or clamp c is forced down by the screw orbolt 0", the outer end of the arm or extension Owill be raised.

D is the plow-point, of any of the usual forms, except that its upperface, in line with the colter end, is provided with a recess or slot,(1', into which theend of the colter-blade G is forced and held by theaction of the clamp 0r lug c in raising the arm or extension 0. 6 Thismode of attaching the blade 0 furnishes a firm support thereforitsentire cutting length, as the end of the blade is firmly held in theslot or recess d, while its upper end is held by the arm or extension 0,clamped between the lugs or projections c and c, the result being thatthe colter-blade has a firm support, and at the same time is readilyremoved for the purpose of repairs, as all that is necessary to be doneis to loosen the clamp or lug c, which 7 allows the lower end of theblade to be raised from the recess (1 and the blade withdrawn bywithdrawing the arm or extension 0 from between the clamps or lugs c c,and when the repairs are made the blade can be replaced by 8 insertingthe arm or extension beneath the locking clamps or lugs and forcing thepoint into the recess (2 by drawing down the lug or clamp c.

E is the landside, of construction.

F is the mold-board, formed as usual.

G are the handles, the inner one of which is attached to the inold-boardon the inside, as usual, and the outer one of which is attached 0 to theend of the plow-beam by a clamping plate, G, in which is a slot, 9, toreceive a bolt, 9, passing through the beam, and, as shown, the handlesare connected together by a cross-piece, g. The attachment of the innerhandle to the plow-beam by the plate G, having the slot 9, enables theplow and handles to be set at different inclinations to the beam, to dowhich all that is necessary is to loosen the bolts a and g and turn theplow as reico quired, and then draw the bolts tight.

H is the clevis, of a U or yoke shape, as

of any of the usual forms usual, and pivotallyattached at its rear endtothe beam by a bolt, h, passing through the beam and the side straps ofthe clevis, so that the forward end of the clevis can be raised andlowered vertically to suit the draft,

, I is a rack attached to the forward end of the plowbeam by a bolt, i,which passes through flanges or plates extending rearwardly from therack, and between which the forward end ofthe plow-beam passes. Theforward edge of the rack I is provided with ratchet-teeth '1; its entirelength, and the rack I, as shown, depends below the under face of theplowbeam.

J is a cylinder or thimble, located between the straps of the clevisforward of the rack-bar I, and mounted on the stem of a bolt, 7c,whichpasses transversely through the clevis. This thimble J has on one side alip,j, and on the opposite side a thumb piece, j, and the lipj isarranged in such relation to the teeth '13 of the rack as that it willengage with the teeth when turned down, and at the same time the underface of the teeth is arranged in such relation to the are of the circledescribed by the end of the lipj as that such lip can be turned up toclear the teeth. The thimble J, located between the arms of the clevis,can be clamped and firmly held in position by the bolt 7c, butis free toturn on the bolt when the nut thereof is loosened, and the clevis isadjusted in any desired position'by loosening the nut of the bolt is, soas to release the thimble J. then turning the thimble through the piece9', to release the lipj from the notch 1', with which' it is engaged,then raising or lowering the forward end of the clevis as may berequired for the line of draft, then throwing the lip 1 down to engagewith the notch t" for the required adjustment, and then locking thethimble by setting down the nut of the bolt in; and when the thimble isthus locked the engagement of the lipj with the notch 12 of the rackwill lock the clevis to the plow-beam in a firm manner, and so that itcannot be raised by the action of the draft,-as when the locking-lip jisdown and v engaged with the notch t it cannot be thrown out ofengagement by the draft, as the draft will not act on the thimble J,which is firmly held by the clamping-bolt 7c.

The device is exceedingly simple, and by its use the clevis can beattached to the plow-beam and adjusted in any desired position withoutany liability of being changed or affected by the draft. The use of .theclamps or lugs c 0 enables a colter tobe rigidly attached in position,and the use of the thimble J and rack I enables the clevis to beadjusted and locked firmly in any position desired for the draft, bothof which features are desirable for the proper operation of the plow.The lower end of the clamp c is supported on aledge, 0 cast or formedwith ,the' standard B, by which a firm bearing is provided for theclamp" in being drawn down to place to raise the arm 0, enabling a lightbolt or screw to be used for this purpose. the ledge for this purpose.

What I claim as new, and desire to secure by Letters Patent, 'is- 1. Theclevis H and rack I, in combination A pin could be used in the place ofwith the thimble J, having the lip j, substantially as and for thepurpose set forth.

2. The clevis H and rack I, in combination with the thimble J,havinglipj and clampingbolt is, substantially as and for the purposespecified.
